The predicted thickness of the ice covering a certain pond in january is given by the formula t = (x − 1)r − 2p, where t is the thickness in centimeters. if the quantity p increases by 1, what will be the change in the predicted thickness of the ice?

The change in the predicted thickness of the ice is -2 or the thickness of ice decreases by 2.

Step-by-step explanation:

Given: The predicted thickness of the ice covering a certain pond in January is given by the formula,

where T is the thickness in centimeters.

If the quantity p increases by 1, then the predicted thickness of the ice covering a certain pond is given by the formula

The change in the predicted thickness of the ice is give by:-

Hence, the change in the predicted thickness of the ice is -2 or the thickness of ice decreases by 2.

answer: 590

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
